Patent ·
OSTI ID:5731040
This paper describes a molybdenum resistor configuration for a superconductor integrated circuit. It comprises: a support; areas of superconductor film covering portions of the support; an at least 50 Angstroms thick titanium film on the areas of superconductor film; a titanium-molybdenum etch stop interface on the titanium film; a molybdenum film on the titanium-molybdenum etch stop interface; and a titanium oxide film on the support covering portions of the support and not covered by the areas of superconductor film.
